James Wagner visits a novel exhibition of painting, "Battle of the Brush" in Bryant Park, NYC.  The show pits "abstract" painters vs. "realist" painters in a tongue-in-cheek mock battle; a clash as obviously senseless as any taking place around the world today. Wagner remarks that the show is "one of the most creative art shows of the year… The work is on view in closed, retrofitted and climate-controlled vitrines (actually, two of the booths which had recently housed The Holiday Shops at Bryant Park). Visitors will be able to see the art, en plein-air, until February 2."
